Serial No. 572,704

1 Claim. (01. 2c1-s0 The invention relates to an aerating device for live bait containers.

live bait and maintaining such it is imperative that the be almost constantly In transporting bait alive prior to its use, water in the container aerated.

The present device contemplates the positive forcing of air into the water in the container at a predetermined rate so that it is positively known that the water is being aerated.

Another object of the invention is to provide a device for aerating live bait containers which can be readily attached to a supporting structure, such as a portion of'an automobile, boat, pier, or dock so that a Wind Wheel thereon mat be turned by .the flow of air, thereby to force air into the live bait container. 7 7

Another object of the invention is to provide a positive displacement pump operated by a wind wheel to force air into a live bait container.

Still another object of the invention is to provide an impeller operated by a wind wheel for forcing air into a live bait container.

Other and further objects of the invention will be readily apparent when the following descrip' tion is considered in connection With the accompanying drawing, wherein:

Fig. l is a diagrammatic View with certain parts in section showing the general combination of the device wherein a positive displace ment pump is illustrated;

Fig. 6 is a section on the line E-B of Fig. 5; and

Fig. '7 is a section on the line 1-1 of Fig. 5.

At the present day it is not uncommon at all for fishermen to obtain live bait at a source a considerable distance from the fishing grounds and the live bait must be transported usually by automobile or boat to the location where it is to be used, and the present device is intended for use in connection with the live bait container so as to aerate the container. The device, as shown in Fig. 1, includes a frame or body 2 which may but preferably has a clamping device illustrated by the legs 3 and 4 which are spaced apart to straddle a supporting structure such as the bumper, window, or other portion of an automobile, boat or pier. The device will be rigidly supported in this manner and may be clamped in place by the screw 5.

The frame or body 2, as illustrated in Fig. 1, has the body 6 which is made up of the cylinder 1 and the piston 8 working in the cylinder. A check valve 9 permits the flow of air into the chamber 1 on the upstroke and forces the air from the chamber through the discharge conduit W on the downstroke. The piston 8 is operated by the piston rod I2 and the pitman rod l3 connected thereto. The pitman rod is in turn connected to the disc 15 having a plurality of eccentric openings IB therein which receive the bolt ll for supporting A p111- rality of these openings 16 are illustrated in Fig. 2 at varying distances from the center I8 of the disc so that connection to different holes will give a different length of stroke for the pump.

The disc 15 is mounted on the rotatable shaft 2% carried by the head 2| of the frame 2. Agear train 22 is mounted in the head and includes the drive gear 23 on the shaft 20 and the drive gear 24 on the shaft 25. While a gear train has been shown, it is obvious that a belt and pulley arrangement or any other suitable type of power -transmission could be substituted therefor.

A wind wheel or propeller 26 is removably connected to the shaft 25 and it is understood that any size propeller may be used. It seems clear that as the propeller is driven by a flow of air passing thereby, it will reciprocate the piston 8 to force air through the conduit it.

It seems obvious that if the device is to be attached to an automobile driven at a relatively high speed, the device may be adjusted by posirod in one of the openings on the other hand, if the device is to be supported upon a pier or dock or a slowly moving boat where there may be a slight flow of air thereby, it may be desirable to either provide a larger propeller 26 or to place the pitman connection in one of the other openings It so as to obtain a longer stroke. It seems clear that the device may be adjusted in this manner to obtain a predetermined or the desired flow of air into the conduit ID.

The conduit I0 is preferably in the form of a hose which may be extended into the bait container 30 and have its lower end 3| projecting beneath the water level so that air would be discharged into the water. This fiow of air tends to circulate the water and to aerate it so as to keep the bait alive.

The invention may take the form of and 4 wherein the shaft 25 carrying the propeller 25 has an impeller wheel 33 therein and wherein the head is modified somewhat to provide an air inlet 34 an air discharge 35 so that the conduit It is connected by the coupling 36 directly to this outlet 35.

The impeller 33 will have the blades 3'! thereon, as illustrated in Fig. 4, so that the air drawn in through the suction inlet 34 will be discharged in a radial direction through the ports. The clamp or supporting structure is the same as prepumping action. The piston 8 is arranged with. recesses 4D in its periphery, so as to provide a passage 40 for the air or the suction stroke to pass the'fiexible sealing member 4!. In this connected.

A port 43 in the cylinder allows for the inlet of air.

60 is also afiixed to this shaft 57 so that it seems obvious that as the propeller 5!! is rotated it will cause the plate 47 to rotate, and in View of the fact that this plate is inclined relative to the axis of the shaft 5! the plate will be caused to wobble and in turn reciprocate the rod l2.

The operation of the mechanism will be the same as that of Fig. 1 and the device may be attached upon the support structure in any desired manner.

What is clai med is:

An aerating device for use in connection with live bait liquid containers comprising a frame of channeled head on said piston rod within said frame, a pair ably secured i of aligned shaft bearings adjusta shaft journaled in said bearings, a wobble plate CONSTANT A. OLIVEROS.
